The vectors in machine learning signify input data, including bias and weight. In the same way, output from a machine-learning model (for example, a predicted class), can be put into vector format. A lowercase v
Machine Learning Techniques -2-Dual Support Vector Machine 2-Dual Support Vector Machine 在实际问题中,我们可能需要映射变换来做出特殊形状的分界线,这种维度的增加常常会使得二次规划问题面临挑战。 这里有很多数学性很强的的过程,需要参考最优化书籍。 首先总体思路,先要将一个有条件的最优化问题转化为无条件...
Calculating the length or magnitude of vectors is often required either directly as a regularization method in machine learning, or as part of broader vector or matrix operations. In this tutorial, you will discover the different ways to calculate vector lengths or magnitudes, called the vector nor...
In machine learning, what is the main purpose of using a support vector machine (SVM)
Machine learning (ML), as a part of artificial intelligence, involves model-building based on sample data, or training data, to “learn" and then to make predictions without an explicit programme. ML is used widely for instance in speech recognition16, computer vision17, social network filtering...
This normalization process is especially vital in machine learning applications, where it aids in removing biases caused by variations in feature scales, thereby significantly improving the predictive performance of models. By ensuring that all data points are evaluated on a consistent scale, data ...

The support-vector network is a new learning machine for two-group classification problems. The machine conceptually implements the following idea: input vectors are non-linearly mapped to a very high-dimension feature space. In this feature space a linear decision surface is constructed. Special pro...
A support vector machine (SVM) is a type ofsupervised learningalgorithm used inmachine learningto solve classification andregressiontasks. SVMs are particularly good at solving binary classification problems, which require classifying the elements of adata setinto two groups. ...
光滑的函数(Smooth Function)f \in \mathcal{C}^{\infty},即f无限次连续可导 T_{\infty}\left( x \right) \triangleq \sum_{k=0}^{\infty}{ \frac{f^{\left( k \right)}\left( x_{0} \right)} {k!} \left( x-x_{0} \right)^{k} } ...
